.MAN, a .citizen of the United States, residing at Newark, in thecountyof Essex' and State of New Jersey, have invented'certain new an'duseful Improvements in Phonic Apparatus, of which the following is fadescription.

My invention relates to phonic apparatus ofthe type wherein a rotatingfriction-wheel is used in combination lwith a` friction-shoe pressedagainst the same, power Vbeing a plied for rotating the friction-wheel,and t e pressure between the friction-shoe and fricap' aratus. zo

instrumentality of a tion-wheel bein varied bywsuitable means-lrepresentative o sound-vibrations, thus producing variations in theamount oi` friction,

which by suitable mechanical connections may ,operate a diaphragmori-.other phonic l ily invention relates more y ar'ticularly to devicesfor reproducing soun sthrough the honographic record,

the phonographic sty us being connected with said frictlon-shoe andAoperatingto varythe amount of friction.

Heretofore, as far as I am aware, the friction-wheel-hasalways beendriven from a stationary motor, and the said friction-wheel has eitherbeen mounted so asf to have no. progresslve motion or 1n case'jit hasbeen mounted on a traveling carrier the driving mechanism has been soarranged that the' friction-Wheel may receive its power from.

the said stationary motor during its move- I Tlent with the carriage.These devices-tare objectionable, however, because they are'not readilyapplicable to an ordinary phonograph and require specialvforms ofinstruments, which are expensive to construct and which in some casescannot be used with an ordinary phonographicspea-ker. My invention hasfor its general objec the provision'of a mechanism of the characterreferred to and more particularly its application to a phonograph oiordinary construction, so that the mechanism may be interchangeable withan ordinary phonographic reproducer without the, addition of any partswhatsoever to the ordinary phonograph. Thisobject has been carried outby the mounting of a complete frictional reproducing. apl aratus upon avbase which is adapted to t within the kordinary car- Specication ofLettersPatent. v.replication nea 0mm-14.1995, serai Nu. 282.710.'
